摘要:
A buffer tube for firearms, including assault rifles, carbines, shotguns, and other rifles is disclosed. The floating buffer tube comprises a recoil mitigation mechanism, including a helical spring or an elastic or viscous energy absorption device, and a buttstock mounting bracket mounted outside the buffer tube. The buttstock mounting bracket can rotate relative to the buffer tube, which changes the axial angle of the buttstock relative to the firearm. The angle can be locked under an expansive force by forcing a bolt or pin into grooves to select the proper axial angle of the buttstock relative to the firearm in the field without the user having to disarm himself to perform the angle change.
摘要:
The present invention relates to a fiber-reinforced cement based or cementitious material, and process for making, where the reinforcing fiber is a chemically treated cellulose or non-cellulose fiber. The fiber reinforced cementitious material includes (i) cement, (ii) optionally, sand, aggregate, or sand and aggregate, and (iii) chemically treated fibers having a polyvalent cation content of from about 0.1 weight percent to about 5.0 weight percent based on the dry weight of the treated fibers. The present invention further provides for a fiber reinforced cementitious material having a weak acid content of from about 0.5 weight percent to about 10 weight percent based on the dry weight of the treated fibers.
摘要:
The mailer assembly is used for direct mail applications. Upon removal of tear strips at each side of the mailer assembly, an insert is formed from a panel secured within the mailer which is able to fall free of the mailer. The mailer assembly may be provided with two or more panels to form two or more free inserts. In one embodiment, the mailer assembly may be constructed with a return envelope into which a free insert may be folded and stuffed.
摘要:
A collapsible buttstock with automatic deployment has a housing with an opening providing clearance for a buffer tube. Rods slidably couple through respective openings in the housing; the rods each having a hollow cavity accommodating biasing structure for exerting a biasing force against a respective attachment member. A locking element has locking blocks, each engaging a respective one of plural notches on the rods, for locking the rods to an operator support buttstock element, each of the locking blocks comprising a tapered surface. A release trigger with a contoured step engages the tapered surfaces of the locking blocks. When the release trigger is moved, the contoured step engages the tapered surfaces to push locking blocks away from engagement with the notches on the rods, thus allowing the biasing member in each rod to push the respective rod and the operator support buttstock element away from the housing.

摘要:
A shotgun shell or low velocity grenade dispenser and reloader system that can quickly and efficiently dispense a shell without requiring the focus of the operator. The dispenser can be attached to the operator's belt, leg, forearm, or a weapon. Alternatively the dispenser may be left unattached. The dispenser delivers a shell in an orientation that allows rapid loading of a weapon with minimal shell manipulation.

Disclosed are absorbent structures including fibers bound with a polyvalent cation-containing compound and superabsorbent polymer particles. The fibers exhibit an ion extraction factor of at least 5%. Also disclosed are multi-strata absorbent structures, such as disposable absorbent articles, including the treated fibers and SAP particles. Further disclosed are methods for preparing absorbent structures including the treated fibers; structures including fibers combined with a polyvalent cation-containing compound; and methods for treating or coating SAP particles with polyvalent cation-containing compounds.
摘要:
A bladed apparatus comprising: a tool having (1) a first end; (2) a second end; and (3) a spine positioned between said first end and said second end, and a handle portion configured to hold said tool, said handle portion being located between said safety ring portion and said blade portion. A safety ring portion may be positioned at the first end, and a blade portion may be positioned at the second end, with the blade portion comprising an inside edge, an outside edge, and a point. The safety ring portion may comprise, along its outer periphery, (a) a mid-lock portion; (b) a thumb lock portion; and (c) a reverse lock portion.
